RUBBER rrnnnroa roo'rwnaa.

Application filed August 21, 1924. Serial No. 733,420.

tion shown in the accompanying drawing, in

which:

Fig. 1. is a bottom plan view of the heel. i Fig. 2 is a similar View with the rotatable member removed.

Fig. 3 is a transverse section on line 3 3, Fig. 1.

Fig. i is a plan of the inner or upper face of the rotatable member.

Fig. 5 is a side elevation of the rotatable member.

Fig. 6 is a perspective of a portion of the circular guideway or track on an enlarged scale, and

Fig. 7 is a side elevation of one of the guide studs or pins enlarged.

The upper fixed or main portion 1 of the heel will be secured to the heel portion of the shoe, not shown, in any suitable manner. The rubber portion of the heel is formed in two sections 2 and 3 by cutting the rubber on the curved line l, as shown in Figs. 1 and 2.

A circular track or guideway formed of a metallic ring 5 is embedded and securely fixed in the main portion 1 of the heel and is formed with an under-cut circular groove or channel 6 having its exposed open portion 7 flush with the lower side or bottom of the heel member 1. This channel 6 has a transverse entrance slotor opening 8.

The circular tread or disk 3 is provided with a circularly arranged series of headed pins or studs, shown in detail in Fig. 7, and each comprising a base 10, shank 11 and head 12.

The bases 10 of these pins or studs are embedded in the circular tread or disk 3 with their heads 12 exposed above the upper or inner face of thetread or disk.

The heads 12 are successively entered into the circular guideway' 6 by pa'ssing said heads through the entrance opening or slot 8 and turning the tread or disk until all of the studs are in the said guideway; the shanks ll lying in the open portion 7 and the heads 10 in the under-cut circular groove or channel 6, where they will be securely held and in turn hold the tread or disk 3 {irmly against the main portion 1 of the reel.

The tread or disk has a centralaperture 14: through which an adjusting screw 15 is passed into the main portion 1, as at 16.

The heel will now appear as in Fig. 1.

- By loosening the screw 15 the rotatable tread or disk 3 may be turned to bring a different portion thereof to the position occupied by the worn portion, and thus the life of the heel may be greatly prolonged and greater comfort afforded the user.

The portions 2 and 3 of the rubber heel are provided as usual with the raised antislipping portions 19.

What I claim is: 1. A heel for footwear comprising a main fixed member, a rotatable disk-like tread, a.

circular under-cut guidcway and a circularly arranged series of headed studs or pins guided in said guideway and said studs.

and guideway adj ustably and rotatably connecting said main" and rotatable treadmen1- bers.

2. A heel for footwear comprising a main fixed member; an annular guideway set flush in the lower face thereof and having an under-cut annular groove open at its lower side, and. a disk-like tread having a circular series of headed pins the shanks of which project through the open side of the annular groove and with their heads lying in the under-cut portion thereof.

3. A heel for footwear comprising a main or fixed member, an annular guideway; set flush with the lower face thereof and having an under-cut annular groove open at its lower side, a disk-like tread having guidepins or studs extending through the open lower side of the guideway and provided with beads lying in the under-cut portion, and a central adjusting screw extending through the tread into the main portion ofthe heel.

1. A connecting means for rotatable heel treads comprising an annular track adapted to beembedded in the fixed member of a heel and formed with an under-cut groove or channel open at its lower side, and a pluhaving a series of pins or studs having heads adapted to successively enter the under-cut groove through said transverse cut-away 15 entrance slot and guide the said tread When rotated.

In testimony whereof I alfix my signature in the presence of two Witnesses.
